Fix deploy steps (#17)

This pull request updates the Python package build process in the GitHub
Actions workflow to use a more streamlined approach with `uv` and
`hatch`. The changes improve the build step by removing unnecessary
commands and ensuring dependencies are upgraded before building.

Build process improvements:

* The build step now upgrades `hatch` via `uv pip install --upgrade
hatch` instead of creating a new virtual environment and installing
`hatch` separately, simplifying dependency management.
* The package is built using `uv run hatch build`, which runs the build
command directly, removing the need for explicit virtual environment
creation and tag listing.
